Thirty-two-year-old Chandrapratap Singh had died after Chauhan shot him in his chest. Khan was inside his house when the incident occurred around 12.20 am on August 14, 2006.
The guards were employed with a security agency called Tops Group. Chauhan was the only armed guard and had an all-India licence issued from Uttar Pradesh.
Singh and another guard called Lakhan were patrolling the area behind the bungalow when Chauhan, 28, dozed off for a while. Singh allegedly chided Chauhan for sleeping on the job and also poked fun at his gun, wondering whether the "rusted'' gun "actually worked."
In a fit of rage, Chauhan put his gun on Singh's chest, saying "this is how my gun works" and pumped a bullet into his chest. Singh was rushed to Bhabha Hospital where he was declared dead.
In court, Chauhan's lawyer argued that he should be held guilty of only culpable homicide since he had killed Singh in a fit of anger.
Public prosecutors Sunil Gonsalves and PS Tavade examined 10 witnesses in the case. Judge Tamboli considered the evidence at hand and convicted Singh for murder.
